        <pre>Description:
Tracking changes pasting to multiple columns generates uses > 5 GB ram (without
undo steps) and takes far to long

Steps to Reproduce:
1. Open Calc
2. Tools -> Options -> Advanced -> Expert configuration -> Search for Undo
Reduce 100 to 0
3. Close & restart
4. Open the attached file
5. Enable tracking changes
6. Copy A1
7. Select column A until W
8. Paste

Actual Results:
A memory consuming process starts

Expected Results:
Undo needs 800 MB; so tracking changes does something wrong
